Hello Renato,

Thank you for the provided code. If I have understood correctly, you are attempting to get/set the Editor's content via reComment.Content property and it is not being recognized, is that correct?

I have run several scenarios with the sample code you have provided us, but unfortunately, the provided server-side code was not enough to reproduce the described issue. Furthermore, I could not find a reference to the editor's content in it and, for this reason, I cannot determine the exact location at which the issue is raised.

Just for the test, I have attempted to and succeeded at getting/setting the Editor's content in both the Init and the Load event of the page.

Could you please provide us with sample code reproducing the issue, so that we can further investigate where and why the problem is appearing? You can refer to the following article for more information on how to isolate it: Isolating a problem in a sample project.

We will be looking forward to receiving feedback from you.

Regards,
Ivaylo

There is one detail, the code behind is in another project...  dont knnow if that can be a problem but the structure was already like this when I got it, I am sending a print screen. User control (Comments.ascx) Code Behind (Comments.cs)

[Renato]

I created a new User Control with the Code Behind on the same project... I put the code inside OnInit inside the CreateChildControl and it still returns reComment.Content empty.

protected override void OnInit(EventArgs e)

        {

            Page.Init += delegate(object sender, EventArgs e_Init)

            {

protected override void CreateChildControls()

        {

The code recognizes the RadEditor but not the content...

 Would be really nice to have some support from Telerik! thanks

Hello Renato,

If the editor has no content initially and you enter something, the editor's property Content will be empty on the init event after a postback. I can assure you that this behavior is expected and normal for the RadEditor due to the ASP.NET page life-cycle nature. Nevertheless you could use the page load event, where the content is loaded from the view-state of the application.

Please follow the next explanation in case of more information needed:

1. Page Init event: In this stage the RadEditor is initialized and cointains in the page as control but the view-state is not loaded, so the editor could not get the text for the content.
2. Page Init Complete event: The view-state is loaded and ready for the controls to get the needed information from it.
3. Page Load event: Here the Radeditor has the content loaded from the view-state, so that it can be set or get as reference.

You could also follow this MSDN help article for more information about the life-cycle events.

I am attaching a sample project using the mentioned three events, so that you could follow it and investigate the content value on each stage of the page.

While investigating this case I found other forum posts about the same issue. I would like to ask to open only one support thread about the same issue, so that we are able to track the information correctly and provide you with a proper solution.

Regards,

Ianko

Hi Ianko, I have a scenario that is unfortunatlly totally different than the example... I have a User Control that is being included in a page without code behind. I will post the 3 files: the page, the User Control and the User Control Code Behind so please let me know if it is possible to retrieve the Content of the RadEditor this way... Thanks!

I noticed that on that line <ClientEvents OnRequestStart="RequestStart" OnResponseEnd="ResponseEnd" />
the ResponseEnd clears the value of the RadEditor, is it possible not to clear the value? Could it be the reason why I cant access the value of the RadEditor in my code behind? pls I need an answer, it's been more than a week that I cant find a solution for this or answers to solve my Telerik problem... Thanks!

Hello Renato,

The mentioned client-side scripts does not implement functionality for clearing the editor's content. They are for showing and hiding the Ajax Loading Panel.

About the reference of the RadEditor in the Code-behind - yes with this setup you could get the editor and it's content. You could follow this setup I have been testing with as well as the sample project that uses it, which is attached to the post:

User control:

<telerik:RadEditor ID="reComment" runat="server"></telerik:RadEditor>

<asp:Button ID="Button1" runat="server" text="PostBack"/>

Code-behind:

protected override void OnLoad(EventArgs e)
{
            base.OnLoad(e);

            if (ScriptManager.GetCurrent(Page) == null)
            {
                ScriptManager sMgr = new ScriptManager();
                Page.Form.Controls.AddAt(0, sMgr);
            }


            if (reComment == null)
            {
                reComment = this.FindControl("reComment") as RadEditor;
            }

            string content = reComment.Content;
            reComment.Content = "Some text " + content;

}

If you still encounter the described problem you could implement a Client-side script that modifies the editor's content on it's load event. For more information you could follow this articles:
    -    Getting familiar with Client-Side API;
    -    Getting a Reference to RadEditor;
    -    OnClientLoad;
    -    get_html;
